Is there a way to enable/disable the WCF trace/logging for a perticular end point without changing the web.config ?
You first need to access the trace object by name, as its defined in the .config file. For example:
TraceSource ts = new TraceSource("System.ServiceModel");
Then you can set the filter level to all, none or anything in between:
ts.Switch.Level = SourceLevels.Off; // nothing
ts.Switch.Level = SourceLevels.All; // everything
ts.Switch.Level = SourceLevels.Warning; //warning or higher
BTW - the TraceSource class is in the System.Diagnostics namespace, so don't forget the appropriate using statement.

Lets say I have applicationA that has 3 property files:
-> applicationA
- datasource.properties
- security.properties
- jms.properties
How do I move all properties to a spring cloud config server and keep them separate?
As of today I have configured the config server that will only read ONE property file as this seems to be the standard way. This file the config server picks up seems to be resolved by using the spring.application.name. In my case it will only read ONE file with this name:
-> applicationA.properties
How can I add the other files to be resolved by the config server?
Not possible in the way how you requested. Spring Cloud Config Server uses NativeEnvironmentRepository which is:
Simple implementation of {#link EnvironmentRepository} that uses a SpringApplication and configuration files located through the normal protocols. The resulting Environment is composed of property sources located using the application name as the config file stem (spring.config.name) and the environment name as a Spring profile.
See: https://github.com/spring-cloud/spring-cloud-config/blob/master/spring-cloud-config-server/src/main/java/org/springframework/cloud/config/server/environment/NativeEnvironmentRepository.java
So basically every time when client request properties from Config Server it creates ConfigurableApplicationContext using SpringApplicationBuilder. And it is launched with next configuration property:
String config = application;
if (!config.startsWith("application")) {
config = "application," + config;
}
list.add("--spring.config.name=" + config);
So possible names for property files will be only application.properties(or .yml) and config client application name that is requesting configuration - in your case applicationA.properties.
But you can "cheat".
In config server configuration you can add such property
spring:
cloud:
config:
server:
git:
search-paths: '{application}, {application}/your-subdirectory'
In this case Config Server will search for same property file names but in few directories and you can use subdirectories to keep your properties separate.
So with configuration above you will be able to load configuration from:
applicationA/application.properies
applicationA/your-subdirectory/application.properies
This can be done.
You need to create your own EnvironmentRepository, which loads your property files.
org.springframework.cloud.config.server.support.AbstractScmAccessor#getSearchLocations
searches for the property files to load :
for (String prof : profiles) {
for (String app : apps) {
String value = location;
if (app != null) {
value = value.replace("{application}", app);
}
if (prof != null) {
value = value.replace("{profile}", prof);
}
if (label != null) {
value = value.replace("{label}", label);
}
if (!value.endsWith("/")) {
value = value + "/";
}
output.addAll(matchingDirectories(dir, value));
}
}
There you could add custom code, that reads the required property files.
The above code matches exactly the behaviour described in the spring docs.
The NativeEnvironmentRepository does NOT access GIT/SCM in any way, so you should use
JGitEnvironmentRepository as base for your own implementation.
As #nmyk pointed out, NativeEnvironmentRepository boots a mini app in order to collect the properties by providing it with - sort of speak - "hardcoded" {appname}.* and application.* supported property file names. (#Stefan Isele - prefabware.com JGitEnvironmentRepository ends up using NativeEnvironmentRepository as well, for that matter).
I have issued a pull request for spring-cloud-config-server 1.4.x, that supports defining additional file names, through a spring.cloud.config.server.searchNames environment property, in the same sense one can do for a single springboot app, as defined in the Externalized Configuration.Application Property Files section of the documentation, using the spring.config.name enviroment property. I hope they review it soon, since it seems many have asked about this feature in stack overflow, and surely many many more search for it and read the currently advised solutions.
It worths mentioning that many ppl advise "abusing" the profile feature to achieve this, which is a bad practice, in my humble opinion, as I describe in this answer
I'm stuck on something I should probably move on from but it's driving me nuts...
I can programmatically update SSL certificate info for a self-hosted WCF service using:
Dim config As Microsoft.Web.Administration.Configuration = _
serverManager.GetApplicationHostConfiguration
site.Bindings.Clear()
Dim binding = site.Bindings.Add(ipport, cert.GetCertHash, store.Name)
serverManager.CommitChanges()
and can also change sections of my local web.config using a known file path starting with:
Dim cfg As System.Configuration.Configuration = _
System.Web.Configuration.WebConfigurationManager.OpenMappedWebConfiguration(ConfigFileMap, target)
but if I try to drill down to system.webServer/security/access using:
Dim accessSection = cfg.GetSection("system.webServer/security")
I get Nothing/null and further digging helpfully produces this status for the section "System.Configuration.IgnoreSection", which apparently indicates that System.Configuration doesn't want to play nice with that specific piece - even though it's not denied access in applicationHost as near as I can tell.
On the other hand, if I try to use Microsoft.Web.Administration I can only figure out how to make the change to applicationHost.config, not to the local web.config.
The only thing that seems to want to put the client certificate requirement (sslFlags setting) in the local web.config is IIS Manager (which also doesn't show the setting correctly if it is located in the applicationHost.config)
Obviously there are all sorts of ways to do this but I can't believe there isn't a simple dot net way (other than editing the xml). Does anyone know what the heck I am doing wrong?
Doh!!! Apparently I need to learn to read the manual (although MS doesn't make it easy).
You can simply do:
Using serverManager As New ServerManager
Dim config As Microsoft.Web.Administration.Configuration = _
serverManager.GetWebConfiguration("site name", "/application")
Dim accessSection As Microsoft.Web.Administration.ConfigurationSection = _
config.GetSection("system.webServer/security/access")
accessSection("sslFlags") = "Ssl,SslRequireCert"
serverManager.CommitChanges()
End Using

I created my vb.net project to .exe file.
During installation on another machine, one can change the location of installing package to any drive.
In my project, I have set my app.config to point the Database that is available in c:\project.
If I suppose, while installation, when I change the location of installation to **d:** or anywhere, I get invalid access db.
What I want is:
I want to reconfigure my app.config file automatically, by detecting its current db location.
Imports System.Configuration
Imports System.Configuration.ConfigurationManager
Dim config As System.Configuration.Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
config.ConnectionStrings.ConnectionStrings("MyProject.Properties.Settings.MyProjectConString").ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;DataSource=|DataDirectory|\SampleDB;Persist Security Info=True;"
config.Save(ConfigurationSaveMode.Modified)
Where MyProject.Properties.Settings.MyProjectConString is the name of your project and connection string.
Although this is too late to answer as the question is very old but I think this might help someone else in the future.
So, there is a way to change the Connection String value in the runtime. Since connection string is a read-only item like all other items that are on Application Scope under My.Settings so we can't change it using My.Setting.ConnectionString = "Something". But here is the code by which you can solve the issue and change any My.Settings item that is on Application Scope in the runtime.
So the code is,
My.Settings.Item("ConnectionString") = "Something"
simple...
MsgBox(My.Settings.Item("remoteAddress").ToString)
My.Settings.Item("remoteAddress") = "abcserver.servebbs.net"
My.Settings.Save()
MsgBox(My.Settings.Item("remoteAddress").ToString)
You have three options:
1.) Create and use a folder in C:\Databse and set your connection string at design time.
2.)Add the database to the project's data source at design time, then use '|Data Directory|\mydb.mdb' as your connection string.
3.) And if you use sqlserver, you don't need to worry about the location of the database once you have attached the database to sqlserver. You only need to use the proper connection string eg 'Data Source=.; Database = mydb; Integrated Security = False; Username=myusername; Password = mypassword; User Instance = false'.
The above is an example of a sql server with SQL Authentication mode as login, if you use Windows Authentication, set Integrated Security = True and remove both username and password.
ORM settings in Coldfusion application.cfc run before anything else runs (onapplicationstart, etc). So how do you set a dynamic datasource (code before the ORM init) in application.cfc? we can set it after and it re-points the ORM to a dynamic datasource, but that requires that the hardcoded datasource must be valid as well. This is tenuous at best.
Here is an example:
<cfscript>
this.name = "someapp_#hash(cgi.http_host)#";
this.ormenabled = "true";
this.ormsettings = { cfclocation = "config/definitions", eventhandling = "true",datasource="STATICDATASOURCE" };
</cfscript>
If it's not specified in application.cfc scope then you get errors like "ORM is not configured for the current application."
We need to be able to get the datasource from a text file on the server.
this.datasource="YourDatasourceName";
Well, if you wanted to store a file, for this example we'll call it "datasource.xml" consisting of:
<dataSourceName>Name goes here</dataSourceName>
You can read it in with:
dataFile = fileRead("pathToFile/datasource.xml");
data = xmlParse(dataFile);
dataSourceName = data.dataSourceName.xmlText;
this.datasource=dataSourceName;
ORM datasource just uses the default datasource if not defined.
Having said that, if you want to add / remove datasource dynamically, see Administrator API at: http://help.adobe.com/en_US/ColdFusion/9.0/Admin/WSc3ff6d0ea77859461172e0811cbf364104-7fcf.html (available since CF8)
I'm not sure if you can re-set the this.ormsettings.datasource to something else at runtime (i.e. onApplicationStart()? or onServerStart()?), but many of the settings can be set again. You may want to try it out.
So I currently have 2 WSDLs added as Service References in my solution. They look like this in my app.config file (I removed the "bindings" field, because it's uninteresting):
<system.serviceModel>
<client>
<endpoint address="http://localhost:8080/query-service/jse" binding="basicHttpBinding" bindingConfiguration="QueryBinding" contract="QueryService.Query" name="QueryPort" />
<endpoint address="http://localhost:8080/dataimport-service/jse" binding="basicHttpBinding" bindingConfiguration="DataImportBinding" contract="DataService.DataImport" name="DataImportPort" />
</client>
</system.serviceModel>
When I utilize a WSDL, it looks something like this:
using (DataService.DataClient dClient = new DataService.DataClient())
{
DataService.importTask impt = new DataService.importTask();
impt.String_1 = "someData";
DataService.importResponse imptr = dClient.importTask(impt);
}
In the "using" statement, when instantiating the DataClient object, I have 5 constructors available to me. In this scenario, I use the default constructor:
new DataService.DataClient()
which uses the built-in Endpoint Address string, which I assume is pulled from app.config. But I want the user of the application to have the option to change this value.
1) What's the best/easiest way of programatically obtaining this string?
2) Then, once I've allowed the user to edit and test the value, where should I store it?
I'd prefer having it be stored in a place (like app.config or equivalent) so that there is no need for checking whether the value exists or not and whether I should be using an alternate constructor. (Looking to keep my code tight, ya know?)
Any ideas? Suggestions?
EDIT
Maybe I should ask about these Alternate constructors as well.
For example, one of them looks like this:
new DataService.DataClient(string endPointConfigurationName,
string remoteAddress)
What values could get passed for "endPointConfigurationName" and "remoteAddress"?
EDIT2
Answering my own questions here, the "endPointConfigurationName" appears to be the same as the "name" in the app.config XML and the "remoteAddress" is formatted the same as "endpoint address" in the app.config XML.
Also! The answer to my first question about getting the EndPointAddresses is the following:
ClientSection clSection =
ConfigurationManager.GetSection("system.serviceModel/client") as ClientSection;
ChannelEndpointElementCollection endpointCollection =
clSection.ElementInformation.Properties[string.Empty].Value as ChannelEndpointElementCollection;
Dictionary<string, string> nameAddressDictionary =
new Dictionary<string, string>();
foreach (ChannelEndpointElement endpointElement in endpointCollection)
{
nameAddressDictionary.Add(endpointElement.Name,
endpointElement.Address.ToString());
}
EDIT3
Ok, I think I've figured out the 2nd half (and thus, full solution) to my problem. I found this on another website and I modified it to meet my needs:
Configuration configuration;
ServiceModelSectionGroup serviceModelSectionGroup;
ClientSection clientSection;
configuration =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
serviceModelSectionGroup =
ServiceModelSectionGroup.GetSectionGroup(configuration);
clientSection = serviceModelSectionGroup.Client;
foreach (ChannelEndpointElement endPt in clientSection.Endpoints)
{
MessageBox.Show(endPt.Name + " = " + endPt.Address);
}
configuration.Save();
With this code, we have access to the clientSection.Endpoints and can access and change all the member properties, like "Address". And then when we're done changing them, we can do configuration.Save() and all the values get written out to a user file.
Now here's the catch. In debug mode, the "configuration.save()" does not appear to actually persist your values from execution to execution, but when running the application normal (outside of debug mode), the values persist. (Which is good.) So that's the only caveat.
EDIT4
There is another caveat. The changes made to the WSDLs do not take effect during runtime. The application needs to be restarted to re-read the user config file values into memory (apparently.)
The only other thing that I might be interested in is finding a way (once the values have been changed) to revert the values to their defaults. Sure, you can probably delete the user file, but that deletes all of the custom settings.
Any ideas?
EDIT5
I'm thinking Dependency Injection might be perfect here, but need to research it more...
EDIT 6
I don't have comment privileges but you need to run
ConfigurationManager.RefreshSection("client");
to have the cache updated so that changes happen immediately.
If you're using Microsoft Add Web Reference to create your service reference, then I think you may have trouble changing the connection programmatically. Even if you did change the auto generated code, as soon as you did an Update Service Reference it'd be overwritten.
You're best bet is to scratch Microsoft's auto generated code and build your own WCF classes. It's not difficult, and offers lots of flexibility / scalability.
Here's an excellent article on this very subject.
As for storing the custom addresses, it would depend on your app whether it's a Silverlight, Windows or web app. My personal choice is the database.
